EDWALL MILLS, OF SAN FRANCISCO, CALIFORNIA.

To all 107mm it may concern Be it known1 that I, EDWARD J. MILLS, a citizen of the United States, residing in the city and county of San AFrancisco and State of California, have invented certain new and useful Improvements in Indexes for Bound Books, of which the following is a specification. a The hereinafter described invention relates to an index which j j plied to and detached from bound books, the same comprising a pluralitycf index sheets detachably held in adjusted position between theV leaves of a book, .and a back plate to which the said sheets are removably connected by means of suitable connecting means; the object of the invention being the production Iof index sheets which may be applied between the leaves of a bound book without in any manner interfering with the binding the same and a supporting or base plate being such that the leaves may be removed at will from one book and applied to another book. i

The invention is mainly designed as an books for securing ready reference alphabetically to the names of the subscribers and equally so tothe classification of advertising matter' contained therein, which telephone directory books are usually re-issued three or four times a year.

By the use of the present invention, they .index may be quickly detached from an old or discarded telephone book and quickly applied to a new or reissued telephone book, so that a' single index maybe used repeatedly fora large number of re-issued books, and this Without in any manner injuring the bound book; v

To' comprehend the invention reference should be had to the accompanying sheet of drawings, wherein- Figure 171 is a plan view of a directory in open position illustrating the index applied thereto. Fig. 2 is a rear view disclosing the position of the base plate relative to the back of the binding of the book. Fig. 3 is a broken plan view of the base plate and the clamp rings carried thereby. Fig. 4 is y a side view of one of the clamp rings, the

same being dotted lines'. I

The index comprises a plurality of sheets indicated in open position hy INDEX FOR BOUND BOOKS.

as shown at 3, so that said edgeof the sheet back ofthe binding 5 of the book in which .clearance space 6, Fig. l of the drawings, through which the leaves ofthe book may be passed in case a. mistake should be made fin positionin thel index sheets within thebook.

will be removed a slight distance from the the index sheets are located andiprovide' a The in ex tabs of the. series of `index stamped alphabetically, the'tab j dex sheet, so that the letters of the alphabet to a. base plate 7 by means of theclamp rings are united to the ends` 9 of the base plate 7 and extend through the perforations l0 of the stub extensions/1. The plate 7 isV made somewhat-longer than 8, which rings while the index sheets l are out to the size of the book leaves between which theyare to be applied, except that the front tab section 2 and the rear stub section 4 project beyond the respective edges of the book. I

In applying the index to a telephone book, the base plate 7 is secured to the back of the binding 5 of the book in any suitable manner, as for instance, by a wire connection',

leaves of the' book centrally thereof and the ends being passed through the back of the binding of the book and the spaced perforations 12 of the base plate and then turned down so as to hold the base no t permanently to the back of the binding 5 'of the book 14 to which the index is to be applied, the clamp rings 8 being` in openposition. The book is then opened to the commencement of the subscribers name` falling under the letter A of the alphabet and the index sheet having the tab extension stamped with the letter A inserted, its perforated stub extension being strung on the open the subscribers whose names commpnce with the book, to which the index is to be applied,

the main body of which lies between the plate firmly but rings 8. The leaves are then turned over to 3, when the index sheet having its tab extension stamped with the letter' B is inserted, its perforated stub extension being likewise strung on the open clamp rings 8.- This mannerl of inserting the index sheets is continued until all have been inserted alphabetically Within the book, after which the clamp rings are closed to hold the said sheets in locked position relative to the leaves of the directory. l

On a new telephone directory being issued to the subscribers the index shectsare removed from the old directory. For this purpose, theclamp rings are opened and the index sheets removed therefrom, the Wire connection 1l being then detach/ed from the base lplate 7 to release the same from the book, when the plate is applied to the new 'j dex sheets are made directory and the index sheets inserted as be fore described. 'By preference, each of the sheets 1 ismade of a size to cover the leaf of the, book to which it is applied, thereby gaining considerable surface for the placin of advertising matter throughout the boo to which the index sheets are applied. However, the saidsheets may be constructed in any given .mannen this being left optional 'with the manufacturer. Preferably, the inof light cardboard, which tends to strengthen the bound book, but the material from which the indexsheets are made may be variedas desired.

Under the described invention there is produced a simple, effective, inexpensive and durable removable alphabetical index for bound books, the same being readily applied to and detached from the book and this Without the necessity of the leaves being loosely bound Within the book, as in the case of loose lea-f books.

While I have illustrated and described the preferred embodiment of the invention, I do-not Wish to be understood as limitinff myself to the details of construction antd the arrangement of the parts as described, being fully aware that the same may be varie without creating a departure from the na ture and scope of the invention.

Having thus described the invention What is claimed as new and desired to be protected by Letters Patent is 1. An index" for bound books, the same `comprising a plurality of index sheets for insertion between the leaves of a book in spaced relation thereto and each provided with a protecting tab containing a letter indicative of the alphabetical position of the sheet relative to the leaves of the book, a perforated stub extension projected from upper and bottom edge of each'sheet adjacent the rear edgethereof to extend a slight distance beyond the said edges of the bock, a base plate for engaging the outer surfaceof the back of the binding of the book and of a length to project at each end sheet relative to the leaves o the tab of successive sheets extending` a the a slight distance beyond the same, and means for detachably connecting tbe lprojecting ends of said plate with the perforated stub extensiony of each index sheet.
